Lifting Mechanism

tube] oil coalescers, equipment transportation, and rapid lowering and

braking of load during handling operations. Bolt separator [and

accessories] to weld-fabricated, structural steel skid base, or mount on

manufacturer's standard base.

2.2.1

Lifting Mechanism

**************************************************************************

NOTE: For units fabricated from fiberglass, specify

straps. In a salt water environment substitute

acceptable non-corroding metal such as but not

limited to copper-nickel, 316 stainless steel, or

monel. Aluminum is unacceptable. Consult

manufacturers' data.

**************************************************************************

Fit separator with lifting [lugs] [straps] [padeyes] [supports] for

handling and installation. Each [lug] [strap] [padeye] [support] shall

carry the total dry weight of the separator and attendant appurtenances.

Prominently display lifting instructions on [anodized aluminum] [_____]

plate located on outside of separator.

2.2.2

Flanges

Use only flat face flanges and drill 1,034 kPa 150 pound ANSI Standard bolt

circle and remove burrs. Use flanged piping connections that conform to

ASME B16.5, welding neck type.

2.2.3

Weirs

**************************************************************************

NOTE: Insert suitable material if carbon steel is

not acceptable. Consult manufacturers' data.

**************************************************************************

NOTE: Angle of slope of hopper bottom shall be

greater than the angle of repose of the stored

material. Volume and angle of repose for solids

collected to be determined by designer based on

oil-in-water mixture characteristics and frequency

of cleaning.

**************************************************************************

Attach stationary weirs and adjustable weir supports to separator side

walls to provide a watertight seal between adjoining compartments and

trough to prevent hydraulic short-circuiting. Use carbon steel [_____] for

weir plates and baffles. Provide sharp crested weirs of size and section

specified by manufacture. Provide slotted holes in weir plates and baffles

or supports to permit horizontal and vertical adjustment of weir or baffle.

Use nondeteriorating sealant or gaskets for mounting weir plates. Fill

voids between separator wall and weir plate with sealant to make watertight.

2.2.4

Low Point Drains

Provide means at low points for dewatering separator.
